To all whom it may concern.'

Be it known that I, EDWARD THOMAS POL- LARD, of 7E Hyde Park Mansions,I-Iighbury,

London, England, have invented certain new and useful Improvements inand Connected with Shaping-Machines for Hats and the Like, of which thefollowing is a specification.

This invention relates to improvements in shaping machines for theproduction of wire frames for hats and the like, and has for its objectto expedite the making of the same and to facilitate their removal afterbeing formed, and so obtaining a much greater output, thereby reducingthe cost of production.

The invention consists of an upright stand or support provided with asole plate, and carryinga spindle,which has a removable top, withsuitable cuts or notches over which the wire requisite for constitutingthe frame, or shape is carried, when the frame, or shape is to be formedwith a crown. Around this stand, but independent of it, is fitted acircular disk, or cam plate, suitably notohed or recessed on itsunderside, and formed on its outer edge with cam shaped surfaces, andhaving an operating lever forming part thereof. Immediately under thiscircular disk or cam plate and concentric with it is another circulardisk, which is part of the aforesaid stand, formed with snugs, or eyes,to which a series of arms or levers are pivoted. These said arms orlevers are formed with two sets of suitable projections, which engagewith the notched or recessed underside and also with the cam shapedsurfaces on the outer edge of the aforementioned 4cam plate. Bolted orotherwise connected to each of these arms or levers are two, three, ormore adjustably slotted arms, or fingers, which are capable of beingarranged at different heights and angles, and having hook ends to holdthe wire, which constitutes the frame or shape during the formationthereof. In forming the frame or shape. the said wire is carried in thehollow of the hooks of such of these slotted fingers as are necessary toobtain the desired frame or shape, and when complete, and the frame orshape of the hat, or the like, is to be removed the fingers are allmoved toward the center by means of the operating lever on the camplate. This cam plate acts on the one set of projections of the arms orlevers aforementioned, the said projections are those which engage withthe recesses on the underside of the cam plate. This action of the camplate depresses the projections on the ends of the arms, which arebeyond the points where the said arms are pivoted to the snugs or eyes,on the circular disk, which forms part of the stand aforementioned. Theraising of these arms about their pivots causes all the fingers, whichare fastened thereto, to move inward toward the center, thus allowingthe frame or shape to be freely lifted off.

The cam shaped surfaces on the outer edge of the aforementioned earnplate are so formed that they are forced up against the other set ofprojections, on the arms or levers (which are pivoted to the stand),when the arms or levers are in their normal position, thus locking them.When the operating lever is moved this rotates the cam plate, thustilting the said arms or levers upward, and throwing the last mentionedset of projections on the said arms or levers inward. As the cam platerotates thus, the cam shaped surfaces on its outer edge so fall away, asto allow of the last mentioned set of projections moving inward withoutobstruction.

In order that my invention may be fully understood and readily carriedinto effect, I have hereunto appended two explanatory sheets ofdrawings, of which- Figure 1 is part elevation and part vertical sectionof the stand or shaping machine embodying my invention. Fig. 2 is a planand part horizontal section taken on the line a, b, Fig. l. with thefingers removed. Fig. 3 is a plan with side View respectively of the camand operating handle forming part of the mechanism hereafter more fullyreferred to and described.

The said stand B carries a circular disk, or cam plate F, havingnotches, or recesses (-lformed on its underside. as seen in Figs. 1 and3, which engage with the one set of projections on the levers H1, sothat when the cam plate F is rotated by means of the operating lever K.the aforesaid projections, on the levers H1, are depressed by theratchet like nature of the notches G'. Beneath this disk F is anotherdisk I-l, forming part of the stand B. shown in dotted lines Figs. 1 and2. This disk carries the snugs or eyes to which the arms or levers H1are pivoted. When these arms or levers H1 are pivoted in positions, theprojections on their inner ends, which engage with the notches orrecesses G in the cam plate F stand above this last mentioned disk H.Also on these same levers, when in the above mentioned position, theshoulders J on the levers H1 are in contact with the cam shaped outeredge 1 of the cam plate J the surface of contact being that part of thecam shaped surface farther away from the center. The shoulders J on thelevers Hl being thus prevented from moving inward, the levers H1 cannotmove upward, they are locked until the cam plate F is moved through therequisite arc, thus moving away the cam surfaces in contact with theshoulder J, and allowing the said shoulder to move unobstructed inward.

The notches or recesses G in cam plate F are designed ratchet fashion,to engage with' the inmost projections on arms or levers H1 so that whenthe cam plate F is moved through the above mentioned arc theseprojections are depressed, thus raising the outer ends of arms H1 andmoving the fingers L inward toward the center if the fingers L in Fig. 1were thus moved toward the center, it will be seen that the wire form orshape of the hat or the like could be lifted off without obstruction.

The levers or arms H1 are hinged or pivoted to the disk H forming partof stand B at the point M, while the lower or heel eX- tensions H2 areprovided with adjusting screws N when the machine is 'in the lockedposition, as seen in Fig. 1, these screws N are adjusted by beingscrewed against the stand B thus forcing the shoulders J on arms H1 onto the cam surface thus taking up any wear and preventing any play orshake in the levers H1.

The fingers L consisting of six for each arm are each formed with ahorizontal slot L1 as seen in Fig. 1, and a bolt or stud passes throughthe slot L1 of the finger L connecting it to the arm H1, and a nut Pretains it in position, as seen in Figs. 1 and 2. rlfhe object of thesaid slot L1 is to enable the fingers L being raised or lowered todifferent heights and angles to suit the kind of frame required to beformed. The said fingers L have their upper extremities formed in theshape of a hook L2 designed to hold the wire Q, which constitutes theframe of the hatduring the formation.

1t will be seen in Fig. 2 that though the machine embodying myimprovements is designed with eight arms or levers, a greater or lessnumber may be used to suit various requirements.
